Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to an unmanned tracked robot used for farming and sowing. Background Technology

[0002] A seeder is a planting machine that sows crop seeds. Seeders used for a certain type or type of crop are often named after the crop variety.

[0003] Traditional farming methods often result in seeds not being evenly distributed in furrows, leading to either overly concentrated or unevenly dispersed seeds. This compromises the uniformity of seed distribution in the field, hindering even crop growth and making it unsuitable for large-scale agricultural production. Furthermore, sowing in diverse terrains, such as mountains, hills, and slopes, is challenging. Traditional sowing equipment, including wheeled seeders and small devices like hand tractors, is problematic. Wheeled seeders are prone to slipping and getting stuck in muddy, potholed, or steep terrain, exhibiting poor maneuverability. While hand tractors offer greater flexibility, they are difficult to operate and unstable in areas with steep slopes or undulating terrain. Therefore, traditional farming methods struggle to navigate complex terrain, hindering timely sowing.

[0004] In traditional farming, it is impossible to cover freshly sown seeds with soil. As a result, the soil surface is exposed to the elements for a long time after sowing, which increases the degree of wind and water erosion. At the same time, the seeds are directly exposed to the external environment, making them vulnerable to being pecked by birds, rodents and other animals.

[0005] In comparison with traditional sowing equipment, it is impossible to sow within an adjustable range according to the width of the furrows. Therefore, when the furrows are too wide, traditional sowing equipment cannot fill them completely, and it cannot cover the seeds with soil immediately after sowing. This increases the need for manual intervention and reduces the continuity and efficiency of the sowing operation.

[0006] To address this, an unmanned tracked robot for agricultural sowing is proposed. Summary of the Invention

[0007] The purpose of this invention is to provide an unmanned tracked robot for agricultural sowing, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an unmanned tracked robot for agricultural sowing, comprising an unmanned tracked sowing vehicle, a trapezoidal block fixedly connected to the top of the unmanned tracked sowing vehicle, a fixed horizontal plate fixedly connected to the side wall of the trapezoidal block, a centrifugal sowing assembly disposed on the top of the fixed horizontal plate, the centrifugal sowing assembly comprising a stepper motor fixedly connected to the side wall of the trapezoidal block, a disc fixedly connected to the output shaft end of the stepper motor, a rotating column rotatably connected to the top of the fixed horizontal plate, a fixed column fixedly connected through the interior of the rotating column, a rotating frame rotatably connected to the outside of the fixed column, a cylinder fixedly connected to the side of the rotating frame away from the fixed column, a sliding rod slidably connected to the end of the cylinder away from the rotating frame, and a sphere fixedly connected to the end of the sliding rod away from the cylinder.

[0009] Furthermore, the centrifugal seeding assembly also includes a sliding groove formed on a disc, a sliding block slidably connected to the center of the disc, an electric telescopic rod fixedly connected to the center of the disc, a cylinder two fixedly connected to the top of the rotating column one, a seeding cylinder fixedly connected to the outer side of the cylinder two, a funnel fixedly connected to the top of the cylinder two, and a seed storage box fixedly connected to the side wall of the trapezoidal block.

[0010] Furthermore, the side wall of the seed storage box is provided with a soil covering assembly, which includes a rotating column two rotatably connected to the side wall of the seed storage box. A tripod is fixedly connected to the outer side of the rotating column two. A fixing rod one is fixedly connected to the bottom of the fixing cross plate. A fixing rod two is fixedly connected to the side of the rotating column two away from the seed storage box. A soil storage box is fixedly connected to the side wall of the seed storage box. A soil discharge pipe is fixedly connected to the bottom of the soil storage box. A flipping circular plate is rotatably connected to the outer side of the soil discharge pipe.

[0011] Furthermore, the soil covering assembly also includes a connecting rod fixedly connected to the bottom of the tripod, a distance sensor is installed at the bottom of the fixed rod, and a rubber plate is fixedly connected to the bottom of the connecting rod.

[0012] Furthermore, the sliding block is movably connected to the sphere, and the rotating frame is convex in shape.

[0013] Furthermore, the sidewall of the sliding block is fixedly connected to the output shaft end of the electric telescopic rod, and the top of the funnel is in contact with the bottom of the seed storage box.

[0014] Furthermore, the outer side of the seeding cylinder is located inside the tripod, and the outer side of the seeding cylinder is in contact with the side wall of the tripod.

[0015] Furthermore, the distance sensor controls the opening and closing of the electric telescopic rod via a controller, and the outer diameter of the flipping circular plate is adapted to the inner diameter of the underground pipe.

[0016] Furthermore, the end of the fixed rod two away from the rotating column two is fixedly connected to the flipping circular plate, and the end of the fixed rod two away from the rotating column two is rotatably connected to the soil-lowering pipe.

[0017] Furthermore, the bottom of the inner cavity of the soil storage box is concave with the center of the soil pipe as a reference.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] The centrifugal seeding component uses centrifugal force to throw the seeds out of the seeding device, allowing them to spread evenly within a certain range. This avoids seeds being too concentrated or unevenly dispersed, ensuring uniform seed distribution in the field and promoting uniform crop growth. The centrifugal seeding device can perform seeding operations at a high speed, greatly improving the seeding speed compared to traditional manual seeding or some low-speed seeding methods. It can complete large-scale seeding tasks in a short time, making it particularly suitable for large-scale agricultural production. It can effectively shorten the seeding cycle and ensure timely planting.

[0020] The soil covering component allows for the covering of freshly sown seeds with soil. Timely soil covering after sowing reduces the exposed area of ​​the soil surface, thus mitigating wind and water erosion. It also prevents seeds from being directly exposed to the external environment, thus preventing birds, rodents, and other animals from pecking at or digging up the seeds.

[0021] By combining the soil covering component and the centrifugal component, compared to the existing centrifugal wheel seeding method where the radius of the centrifugal wheel is relatively fixed and thus the spreading range is relatively fixed, the horizontally reciprocating oscillating seeding cylinder can adjust the oscillation range according to the width of the soil furrows. Therefore, it not only enables adjustable seed spreading based on the width of the soil furrows, but also allows for immediate soil covering after seed sowing, achieving integrated sowing and soil covering operations. This reduces manual intervention and improves the continuity and efficiency of sowing operations. Attached Figure Description

[0037] Please see Figures 1 to 10An embodiment of the present invention is provided: an unmanned tracked robot for agricultural sowing, comprising an unmanned tracked sowing vehicle 1, a trapezoidal block 2 fixedly connected to the top of the unmanned tracked sowing vehicle 1, a fixed horizontal plate 3 fixedly connected to the side wall of the trapezoidal block 2, a centrifugal sowing assembly provided on the top of the fixed horizontal plate 3, the centrifugal sowing assembly including a stepper motor 4 fixedly connected to the side wall of the trapezoidal block 2, a disc 5 fixedly connected to the output shaft end of the stepper motor 4, a rotating column 6 rotatably connected to the top of the fixed horizontal plate 3, a fixed column 7 fixedly connected through the interior of the rotating column 6, a rotating frame 8 rotatably connected to the outside of the fixed column 7, the rotating frame 8 being convex in shape, a cylinder 9 fixedly connected to the side of the rotating frame 8 away from the fixed column 7, a sliding rod 10 slidably connected to the end of the cylinder 9 away from the rotating frame 8, and a ball 11 fixedly connected to the end of the sliding rod 10 away from the cylinder 9.

[0038] The centrifugal seeding assembly also includes a sliding groove 12 eccentrically opened on the disc 5 with the center of the disc 5 as a reference. A sliding block 13 is slidably connected to the middle of the disc 5. The sliding block 13 is movably connected to the ball 11, so that the sliding rod 10 can move in a circle on the sliding block 13 through the ball 11. An electric telescopic rod 14 is fixedly connected to the middle of the disc 5. The side wall of the sliding block 13 is fixedly connected to the output shaft end of the electric telescopic rod 14. A cylinder 15 is fixedly connected to the top of the rotating column 6. A seeding cylinder 16 is fixedly connected to the outside of the cylinder 15. A funnel 17 is fixedly connected to the top of the cylinder 15. The seeding cylinder 16 and the funnel 17 are respectively connected to the cylinder 15. A seed storage box 18 is fixedly connected to the side wall of the trapezoidal block 2. The seed storage box 18 is located above the disc 5. The top of the funnel 17 and the bottom of the seed storage box 18 fit together. The funnel 17 is connected to the seed storage box 18.

[0039] The seed storage box 18 has a soil covering assembly on its side wall. The soil covering assembly includes a rotating column 29 rotatably connected to the side wall of the seed storage box 18. A tripod 20 is fixedly connected to the outer side of the rotating column 29. The outer side of the sowing cylinder 16 is located inside the tripod 20, and the outer side of the sowing cylinder 16 is in close contact with the side wall of the tripod 20. A fixing rod 11 is fixedly connected to the bottom of the fixing plate 3. A fixing rod 22 is fixedly connected to the side of the rotating column 29 away from the seed storage box 18. The side wall of the seed storage box 18... A soil storage box 23 is fixedly connected, and a soil discharge pipe 24 is fixedly connected to the bottom of the soil storage box 23. The end of the second fixing rod 22 away from the second rotating column 19 is rotatably connected to the soil discharge pipe 24. The bottom of the inner cavity of the soil storage box 23 is concave with the center of the soil discharge pipe 24 as a reference. A flipping circular plate 25 is rotatably connected to the outside of the soil discharge pipe 24. The outer diameter of the flipping circular plate 25 is adapted to the inner diameter of the soil discharge pipe 24. The end of the second fixing rod 22 away from the second rotating column 19 is fixedly connected to the flipping circular plate 25.

[0040] The soil covering assembly also includes a connecting rod 27 fixedly connected to the bottom of the tripod 20. A distance sensor 26 is installed at the bottom of the fixed rod 21. The distance sensor 26 calculates the distance to the object by emitting infrared light and then detecting the time of the reflected infrared light. The distance sensor 26 controls the opening and closing of the electric telescopic rod 14 through the controller. A rubber plate 28 is fixedly connected to the bottom of the connecting rod 27.

[0041] The working principle of the above implementation is as follows:

[0042] The initialization steps are as follows:

[0043] The unmanned tracked seeding vehicle 1 drives to the land where it needs to be sown, and the staff fills the inner cavity of the seed storage box 18 with the seeds to be sown. At the same time, the staff fills the soil storage box 23 with leaf mold. Leaf mold is made from fallen leaves, withered grass and other organic matter that has been piled up and decomposed over a long period of time. It is rich in humus, loose and fertile, and has good air permeability and water retention, which is conducive to seed germination and seedling growth.

[0044] The operation steps are as follows:

[0045] The steps for centrifugal seeding are as follows:

[0046] When the unmanned tracked seeder 1, carrying a seed storage box 18 filled with seeds, begins to move along the soil that has already been furrowed, the stepper motor 4 is powered on and starts to start. The output end of the stepper motor 4 begins to rotate and drives the disc 5 to move synchronously. At this time, the rotation of the disc 5 drives the eccentrically set sliding groove 12 on it to move synchronously. Since the electric telescopic rod 14 is currently in the closed state, the sliding block 13 is restricted by the electric telescopic rod 14 and cannot slide on the sliding groove 12. The sliding groove 12 drives the sliding block 13 to perform circular motion around the center of the disc 5. When the sliding block 13 is continuously moving in a circular motion, the sliding block 13 drives the ball 11 to also perform circular motion around the center of the disc 5. The ball 11 then drives the sliding rod 10 to move in an arc.

[0047] Therefore, the sliding rod 10 exhibits an arc-shaped motion, allowing it to continuously slide within the inner cavity of the cylinder 9. This avoids the displacement difference caused by the arc-shaped motion of the sliding rod 10, which could lead to jamming. Consequently, the sliding rod 10 drives the cylinder 9 to move synchronously. This causes the cylinder 9 to drive the rotating frame 8 to rotate vertically about the connection between the fixed column 7 and the rotating frame 8. In the horizontal direction, the cylinder 9 drives the rotating frame 8 to rotate laterally. This causes the rotating frame 8 to rotate laterally. The fixed column 7 then drives the rotating column 6 to rotate horizontally about the connection between the rotating column 6 and the fixed horizontal plate 3. Therefore, the rotating column 6 drives the cylinder 15 to rotate horizontally about the connection between the cylinder 15 and the rotating column 6.

[0048] As described above, the seeds awaiting sowing fall from the inner cavity of the seed storage box 18 into the funnel 17 due to their own gravity. Simultaneously, the seeds awaiting sowing roll vertically downwards from the funnel 17 into the inner cavity of the second cylinder 15. Thus, when the second cylinder 15 reciprocates horizontally with the connection point between it and the rotating column 6 as its center, the seeds inside the second cylinder 15 undergo circular motion around the center of the cylinder 15. Therefore, the seeds awaiting sowing are subjected to centrifugal force from the second cylinder 15. When the seeds are thrown against the inner wall of the seeding cylinder 16 by centrifugal force, the second cylinder 15 drives the seeding cylinder 16 to swing back and forth around the center of the cylinder 15. This allows the seeds to be thrown out of the inner wall of the seeding cylinder 16 again by centrifugal force, and then fall onto the land to be sown by their own gravity. At the same time, the seeds that are constantly shaking in the inner cavity of the second cylinder 15 can disperse any clumps of seeds and prevent them from accumulating in the seeding cylinder 16 and the second cylinder 15.

[0049] The centrifugal seeding component uses centrifugal force to throw the seeds out of the seeding device, allowing them to spread evenly within a certain range. This avoids seeds being too concentrated or unevenly dispersed, ensuring uniform seed distribution in the field and promoting uniform crop growth. The centrifugal seeding device can perform seeding operations at a high speed, greatly improving the seeding speed compared to traditional manual seeding or some low-speed seeding methods. It can complete large-scale seeding tasks in a short time, making it particularly suitable for large-scale agricultural production. It can effectively shorten the seeding cycle and ensure timely planting.

[0050] The centrifugal assembly and the unmanned tracked seeding vehicle 1 work together to enable seeding in different terrain conditions, such as mountains, hills, and slopes. Seeding can be carried out in both flat farmland and complex terrain environments.

[0051] The working steps of the soil covering component are as follows:

[0052] As described above, when the seeding cylinder 16 reciprocates around the center of the second cylinder 15, the seeding cylinder 16 contacts the tripod 20 and drives the tripod 20 to reciprocate around the center of the second rotating column 19. Thus, the tripod 20 drives the second rotating column 19 to reciprocate around its own center. The rotation of the second rotating column 19 drives the second fixed rod 22 to rotate synchronously. The second fixed rod 22 drives the flipping circular plate 25 to rotate continuously inside the soil-lowering pipe 24.

[0053] Therefore, at this moment, the leaf mold in the inner cavity of the soil storage box 23 gathers on the soil-draining pipe 24. In the initial state, the rotating disc 25 isolates the soil-draining pipe 24 from the outside world, and the leaf mold covers the upper surface of the rotating disc 25. When the rotating disc 25 rotates continuously, the rotation of the rotating disc 25 no longer isolates the soil-draining pipe 24 from the outside world. As a result, the leaf mold in the inner cavity of the soil-draining pipe 24 begins to fall down along the surface of the rotating disc 25 due to its own gravity.

[0054] Meanwhile, because the unmanned tracked seeding vehicle 1 is constantly moving, and because the seeding cylinder 16 is lower than the soil pipe 24, the seeds fall onto the land waiting to be sown first, and then the leaf mold covers them after sowing.

[0055] The working steps of the soil covering component and the centrifugal seeding component working together are as follows:

[0056] In real life, the furrows waiting to be sown are often of varying widths. Therefore, during the sowing and covering process, we need to evenly fill the furrows. When facing furrows of different widths, the tracks of the unmanned tracked sowing vehicle 1 travel along the sides of the furrow, so the fixed rod 21 is located in the middle of the furrow. When the distance sensor 26 calculates the distance to the object by emitting infrared light and then detecting the time of the reflected infrared light, the distance sensor 26 calculates the width of the furrow. At this time, the distance sensor 26 controls the electric motor through the controller. When the telescopic rod 14 is activated, if the furrow is too wide, the output shaft of the electric telescopic rod 14 extends after being energized. This pushes the sliding block 13 away from the center of the disc 5, causing it to slide on the sliding groove 12. Therefore, the sliding block 13 is further from the center of the disc 5, resulting in a larger radius of circular motion. Repeating these steps increases the range of the sowing cylinder 16's swing. Simultaneously, as the tripod 20 swings back and forth, it drives the connecting rod 27 to move synchronously. The connecting rod 27 then drives the rubber plate 28 to continuously spread the fallen soil to both sides of the furrow. When the furrow is shorter, the opposite steps are repeated.

[0057] The soil covering component allows for the covering of freshly sown seeds with soil. Timely soil covering after sowing reduces the exposed area of ​​the soil surface, thus mitigating wind and water erosion. It also prevents seeds from being directly exposed to the external environment, thus preventing birds, rodents, and other animals from pecking at or digging up the seeds.

[0058] By combining the soil covering component and the centrifugal component, compared to the existing centrifugal wheel seeding method where the radius of the centrifugal wheel is relatively fixed and thus the spraying range is relatively fixed, the horizontally reciprocating oscillating seeding cylinder 16 can adjust the oscillation range according to the width of the soil furrows. Therefore, it not only enables the adjustable range of seed spraying according to the width of the soil furrows, but also allows for immediate soil covering after seed sowing, realizing integrated sowing and soil covering operations, reducing manual intervention, and improving the continuity and efficiency of sowing operations.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
